Traditional Medicinal Plant Species Belonging to Fabaceae Family in Ethiopia: A Systematic Review

Abstract

There are approximately 213 families of flowering plants in Ethiopia and among them 92 families contain species with medicinal properties. However, there is no compiled information that comprehensively expresses which plant species belong to each family. In the present review, a total of 127 medicinal plant species belonging to Fabaceae family and used to treat various human and livestock diseases were reported from 62 articles (53 published and 9 unpublished journals). Calpurnia aurea (26.7%) and Millettia ferruginea (11.8%) were among the most frequently cited species of Fabaceae followed by Trigonella foenumgraecum (11.02%). The highest numbers of species of Fabaceae (62 species) were reported from Southern Nation Nationalities Peoples (SNNP) region, and 58 species were from Oromia region. Regarding growth habit, the majority were shrubs (43 species) followed by tree (39 species) and herbs (38 species). The frequently used plant parts were leaves (19.7%) roots (17.3%) and the whole plant (16.5%). 40.5 % of the prepared medicinal plant remedies of Fabaceae were administered through the oral methods in different regions of the country. The most commonly treated health problems by species of Fabaceae were: snake bites (25 species), evil eye (19 species) and wounds (18 species) in various regions of the country. From the finding, it was concluded that Fabaceae family is providing a diverse medicinal plant species for the treatment of different human and livestock health care systems in Ethiopia. Thus, further research activities on phytochemical characterization and conservation would be suggested for better utilization from this family.
